  • Patent number: 12270238
    Abstract: A counterbalance hinge assembly includes a cam and compression device that counterbalances a weight of a door or a ramp. The compression device biases against a rotation of the door or ramp. The downward movement of the door or ramp drives cam followers in angled slots or cam surfaces of the cam. The angled slots or cam surfaces include varying angles of incline to correspond to varying torque forces of the door or ramp during the opening or closing movement of the door or ramp.

  • Patent number: 11971878
    Abstract: Systems and methods for supporting both batch processing and streaming data applications, to load and process data incrementally, while providing a near-constantly materialized dataset based on raw blockchain data, are described. For example, the system may receive first on-chain data in a first format via a first input stream, wherein the first on-chain data originates from a blockchain node of a blockchain network. The system may transform the first on-chain data to a second format for storage in a second dataset, wherein the second format comprises an unbounded table.
